New: Regional Time Series Tool

A new web-based SeaBASS Regional Time Series Tool is available under "Get Data" in the main menu. It is designed to visualize and serve time-based comparisons of satellite-to-satellite and in situ measurements.

For a given region, one or more satellite sensors must be selected and then all available satellite and in situ data validation data within the bounds of the study site will be combined for comparison as figures and percent frequency distributions. User options are available to select a measurement product of interest (e.g., Rrs, IOPs, Chl, etc), adjust the data averaging period (weekly, monthly, seasonal), the date range, and other graphing options. Each region has a brief description that includes links to extra information about the primary in situ data sources and a map that shows the boundaries used to define each region. With the click of a button, users may also download the source data.


Transition from FTP to SFTP

Due to security vulnerabilities within FTP (File Transfer Protocol), all FTP-based SeaBASS services, including data submission and FCHECK (via FTP) requests, will be permanently phased out on 19 March 2018.

SFTP (SSH File Transfer Protocol), which offers similar functionality and uses individual accounts for each data submitter, will serve as the replacement.

We have updated our data submission instructions with the new procedures for how SeaBASS data submitters may apply for SFTP access to submit their data to the SeaBASS archive and how to run FCHECK requests via SFTP on SeaBASS data files.

We apologize for any inconvenience these changes may cause.


MATLAB file reader updated

An updated version of the MATLAB SeaBASS file reader (readsb) is available.
